Hey y’all so I’m going to the point: I drive a 2016 fit and I accidentally left the map lights on for almost 24 hours as I worked a long shift in a hospital. Just wanted to know if this will affect my battery? And if so what should I do? I’m aware that some cars turn off the map lights automatically after some time does my particular model do that? Please bear with me

 

go out to your car and turn it off if its on and see if the ignition starts.

 

If the battery is original and in good shape it should take a recharge and be ok but I wouldn't be surprised if it's life has been shortened.

 

It's not a great battery to start with anyways. I've replaced it a few times with bigger ones but my electrical system isn't stock. Others with a stock GK have also replaced the battery.

 

The real question is what do you want to do?
On a 3 year old Honda Fit battery, leaving the map lights on probably did drain the battery.
The questions then become how is the Fit behaving now? Is is starting easily? Do you notice any strain to crank over? Light dimming? Any direct symptoms that the battery is significantly weakened?

Assuming the vehicle is starting, I would take if for a long highway drive. Let it charge up.
Then to me? The only way to really know what condition your battery is in, is to have it tested. Most auto parts places will do this for free. That's really the only way to know.

I own a 2016, but I don't know if the map lights automatically turn off.
How do you know you left them on for 24 hours? If you returned to your vehicle and they were on? I'd assume they didn't turn off.

IMO....I'd get the battery tested, if it fails, or is significantly weakened, I'd get a new battery.

 

If it starts, I'd just keep driving it and not worry too much about it. Might be a good idea to have one of those portable jump start battery packs in case it fails one day. I have them in each of my vehicles. I've never had to use it myself, but have jumped other cars with it.

My 2015 has 84k on it and still starts up. When the battery finally goes, I'll put a 51R.

One thing I did was also replace the map, dome and cargo lights with LED units. They draw a lot less than standard halogens.

 

If memory serves me right most, if not all, Hondas that were equipped with map lights in the last 10 years will not turn off automatically if they were toggled on by an occupant..

^^ Well put. I was about to chime in and basically say the same thing.

I will add though that if you go to a 3rd party location to have the battery checked and solely that.

Also just as a friendly heads up... I've seen many people go to 3rd party locations that do a "charging system" test on cars with a weak or faulty battery and their "test" shows the alternator is not charging. This often happens because most of them don't know that the car is equipped with an electronic load detection system which will only charge the battery under specific load parameters. If those parameters aren't met, the system will see a low charge or no charge at all... thus giving a false failure of the alternator.

 

In my '16, the map lights do not time out.

 

The reason I did not give this type of advice is the OP admission that they work long hours at a hospital.
This sounds like a daily driver, depended on to be THE transportation. With Winter basically here, I'd say find out what condition the battery is in, and if it is at all in the failing range, just replace it.

Those portable jump start units, are a good idea. I have one. I'd recommend everyone have one. But if you have a failing battery, they are just a temporary band-aid.

But really IMO it depends on how the battery tests out.
The map lights in a Fit probably don't demand a great draw.
I would expect it is possible the battery pasts the test. Maybe with a somewhat shortened total lifespan, but perfectly useable for now and the immediate future.
In that case? I agree...just keep driving and don't worry about it...and maybe get one of those portable jump start units just in case.
But given circumstance, and winter approaching, I wouldn't do anything first but have the battery tested.

 

If you manually turn on the map light by pushing them in till it clicks, it won't turn off on it's own. But if you have the map light come on with the dome light automatically (There is a slide switch on EX and up models), then it will turn off after a while.
